This invention relates to improvements in anti-friction bearings, more particularly the type in which cone-shaped rollers, as contradistinguished from balls, are used, and the' 5 invention has for its object to provide, in a manner as hereinafter set forth, a bearing of the class referred to, whereby its construction and arrangement will be such as to provide for a full flow ,of lubricant to prevent burning of the bearing when in active position, and further to simplify the construction of bearings of this type as well as reduce their cost and at the same time provide a, correlation of the elements which will. insure more efficient operation and greater durability of the bearing as an entirety.

Withthe foregoing and other objects in view, the invention consists of thenovel construction, combination and arrangement of scribed and illustrated in-the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations, and modifications 5 can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a front elevation of-an antifriction bearing in accordance with this invention. i

Figure 2 is a section on line 2-2, Figure 1.-

Figure 3 is a front elevation of the cup or 5 race member.

. Figure 4 is a section on line 4-4, Figure 3. Figure 5 is a front elevation of the cone. Figure 6 is a sectiorbon line 6--6, Figure 5. Figure 7 is a fragmentary view, in section,

0 upon an enlarged scale, illustrating the posi- J tion of the roller relative to the cup and C0118:

. Referring to the drawings in detail, each I of the rollers is generally referred to by the reference character 1, the ca e generally by the reference character 2, t e cup or' race member generally by the reference character 3, and the cone generally by the reference character 4:. v

.The cage 2 is annular in form and'consists of two sets ofpivoted links. Each set is of circular contour and indicated at 5. Arranged between and pivotally connected with the sets of links are spacing members 6, which are arranged in spaced relation, provided with curved sides and between each pairv of spacing members 6 is arranged a of an annulus 9 and in cross section the outer side face 10 thereof extends in a straight plane. Each outer corner of the annulus 9 is rounded, as at 11, 12. The front face 13 of the annulus 9 is of less width than the rear face 14 thereof, and the latter is incut to form an annular shoulder 15, which in cross section extends in a plane parallel to 0 parts, as heremafter more specifically dethe plane of the outer side face 10. The

shoulder 15 terminates in an annular ledge 16 which in cross section extends towards the axis of the annulus 9 and inclines forwardly towards the front face 15. The ledge 16 terminates winthe inner side face 17 of the annulus 9, and in cross section said inner side face inclines downwardly from 7 its point of joinder with the ledge 16 to its point of joinder with the front face 13, and

under such conditions the inner'side face of the annulus,9 is bevelled in an inward direction from the rear to the front of the annulus.

at the rear of the race member.

The shoulder 15 in connection with the, ledge 16 provides a lubricant container Thecone 4 is in the formof an annulus I 18 and the inner side face 19 thereof, inv

cross section, extends in a straight lane. The forward inner corner of the annu us 18 is rounded, as at 20, and the rear innercorner thereof is sharp, as at 21. The forward face 22 of the annulus 18, in cross section, extends in a straight plane and which terminates in a rounded outer corner 23, which merges into a peripheral shoulder 24, arranged rearwardly of the front face .22. The. outer side face 25 of the annulus 18, in cross section, extends downwardly upon an inclined plane from the outer'end of the shoulder the forward end of the outer 1 side face of a 'rearwardly extending annular abutment 2 6 of semi-circular cross section throughout. The abutment 26 forms the outer part of the rear face 27 of the annulus.

rand further said abutment has its rear face forming a curved contacting surface for the 'wardly from the point of joinder of the body portion 29 with the head 'to the edge of flan e of the bearing roller. The contactin sur ace is positioned throughout clear of an inwardl with respect to the lane of said outer si e face 25. The rear ace 27 of the with the shoulder 2A.

annulus 18 has the inner part thereof inset forwardly throughout with respect: to the abutment 26 and in cross section said forwardly inset portion is of concave curvature throughout to'form a shallow groove 28. 'As

. the inner part of therear face 27 of the ann nulus is inset with respect to the abutment 26, the rear inner corner 21 of the annulus is arranged forwardly with respect to the abutment 26. The setting up'of the outer side face 25 of the annulus 18, in a manner as stated, provides the cone 4 with abevelled the opening formed between said elements willradually-increase in width from the rear face of said element towards the forward face thereof to provide for the contact of the cup and cone with the cone-shaped rollers positioned therebetween.

Each of the rollers 1 consists, of a frustoconical body portion, 29, gradually decreasing in diameter from the outer towards the inner end thereof, and further having the periphery thereof uninterrupted fromend to end. The length of the body ortion-29 is the same as the width of the inner face 17 of the on or the outer face 25 of the cone,

and when t e roller is mounted in. position, the outer end of the body portion-29 isflush lilach'of the rollers further includes a cirwcular head 30'of substantial thickness and of a diameter greatef than the greatest di-. ameter of the 'body portion 29 to provide a flange extending circumferentially with respect to the body ortion 29. The inner or smaller 'end of the ody portion 29 is formed integral concentrically with respect to the forward face of the head 30. The exposed lect and provide for a full flow of lubricant of the burning 0 portion 31 ofthe forward face lot the head 30 extends upon a slight inclination downthe latter. This slightly tapered or inclined portion ofthejforward face of the head 30' 1s engaged by the rounded. rear outer corner 26 of the cone 4, and acts as a mans to colthrough at the periphery of the body portion 29, hereby; reventing an possibility f the roller. T hewidth of the portion 31 of the forward face of the head 30 is such as to project beyond the shoulder'26 and also to'oppose the ledge 16,

as clearly shown in'Figures 2 and 5.

is mounted on the shaft-onjournal 32, and

the cage 2 with the rollers 1 positioned between the cup 3 and the cone 4. The rollers" 1 extend at opposite inclinations, see Figure 2, and the rounded shoulder 26 is perma' nently in engagement with what may be termed the inner side of the portion 31 of the forward face of the head 30.

The construction and arran ement of the bearing is such-that the shoulder 26 contacts with a very small part of the portion 31 of the forward face of the head 30, and owing to the factthat said portion 31 inclines away from the body portion 29, the head 30 isclear of contact with theledge 16, which materially reduces friction to a minimum between the disk and the cup and cone. Further, the shoulder 26 acts as a means to keep the head 30 from engagement with thd ledge 16, as said shoulder projects slightly beyond the point of joinder: of the ledge 16' with the inner face 17 of the annulus 9. When the parts are set up, the groove 28' not only co lects the lubricant but tends to direct it towards the forward face of.the

head 30 so that it will be taken up thereby and be distributed throughout the periphery of the body portion 26. 7

The cup 3 with its large end constructed in a manner as indicated at 15, 16 forms what may be termed a lubricant collector or reservoir and contributes to a great saving in lubricant. The cone 4, having its inner end constructed in a manner as indithe walls. of the lubricant containen at the rear of the race member. Owing to the posltioning of the lubricant reservoirs or con- 'tainers in the manner as'statedall the movadeing parts of the bearingv are freel i luatlely and continuously lubricated:

the roller presses The rollenand the cone.

The body ortion "29 j of flange formed shoulder 26of the cone coacts to provide The flanges or or flange 30 on the'inner' end of I uarely up against the thrust portion 26' o the cone 4, this will give a true rollinglinecontactbetWeen the the roller, the-- by. the=- head 30 and the a true line contact for endlthrushand a continuous true line rolling contactfrom the the roller and with such contacts in the form When the bearing is set up, the cont 4of"aT-square, that is say a. contact fol-' head. 30 male end of the body portion of lowing transversely the flange of the head 30 and shoulder at the rear end of the cone and head of roll, gives a line contact the transverse length of flange covering face of cone. The rolling line between cam and roll body line is a square line, being so separated by the end thrust line. a T rolling line of contact, being squaredby such. Its formation cannot be otherwise than a T-square' rolling line contact, since the head of the roller is larger than any other part of the roller, it provides for roller running in true rolling line, which is important for high speed. The transverse line of contact revents deviation of the body portion of t e roller whereby the latter will be retained in true rolling, line at all times under such conditions reducing friction to a minimum.

It is thought that the many advantages of an anti-friction bearing of the cone type,

' bination with a bearin in accordance with this invention, can bereadily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be un derstood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.
